Qobuz joins Tidal and Deezer as a first-class playlist sync source.
New Qobuz tab on the Sync page lists user playlists + a virtual
Favorite Tracks entry, and clicks route through the same discovery →
sync → download pipeline the other services already use.
Backend:
* core/qobuz_client.py — new get_user_playlists, get_playlist,
get_user_favorite_tracks, get_user_favorite_tracks_count. Returns
normalized dicts (matches Deezer client shape, not Tidal's
dataclasses) so the discovery worker can iterate directly without
duck-typing. Virtual `qobuz-favorites` ID dispatches to favorites
fetcher inside get_playlist — same trick Tidal uses with
COLLECTION_PLAYLIST_ID. Both list endpoints paginate against
Qobuz's 500-cap limit.
* core/discovery/qobuz.py — new worker module. Mirrors
core/discovery/deezer.py: pause enrichment, iterate tracks,
hit discovery cache, fall back to _search_spotify_for_tidal_track,
build wing-it stub on miss, sync results to mirrored playlist.
* web_server.py — adds /api/qobuz/playlists, /playlist/<id>,
/discovery/start/<id>, /discovery/status/<id>, /discovery/update_match,
/playlists/states, /state/<id>, /reset/<id>, /delete/<id>,
/update_phase/<id>, /sync/start/<id>, /sync/status/<id>,
/sync/cancel/<id>. One-for-one with the Tidal + Deezer endpoint
sets. Qobuz discovery executor registered for clean shutdown.
Frontend:
* webui/static/sync-services.js — full handler set (loadQobuzPlaylists,
createQobuzCard, openQobuzDiscoveryModal, startQobuzDiscoveryPolling,
startQobuzPlaylistSync, startQobuzSyncPolling, cancelQobuzSync,
startQobuzDownloadMissing, rehydrateQobuzDownloadModal, etc.).
Reuses the shared YouTube discovery modal via fake `qobuz_<id>`
urlHash and is_qobuz_playlist flag. Shared switch statements in
getModalActionButtons / generateTableRowsFromState / Wing It helpers
in downloads.js gain new isQobuz branches alongside the existing
per-service ones.
* webui/index.html — new Qobuz tab button + content div, slotted
between Deezer and Deezer Link.
* webui/static/style.css — new .qobuz-icon for the tab icon.
* webui/static/core.js — qobuzPlaylists / qobuzPlaylistStates /
qobuzPlaylistsLoaded globals.
Followed the existing per-service pattern verbatim rather than
refactoring the duplicated transformers across Tidal / Deezer /
Spotify-public / YouTube / Mirrored — that refactor is its own follow-up
PR per the "don't break Tidal/Deezer" scope discipline. Adding the 6th
copy of a proven pattern is lower risk than collapsing 5 working
services behind a new abstraction.
Tests:
* tests/test_qobuz_playlists.py — 12 tests covering pagination,
normalization, favorites virtual-ID routing, artist-name fallback
chain (performer → album.artist → 'Unknown Artist'), and
unauthenticated short-circuits.
